FROG.

Application filed December 31, 1921.

This invention relates to railway frogs and has for its object to provide a new and improved device of this description. One of the objects of the present invention is to provide a frog having a main body partially or wholly of cast or forged parts which are `fastened together and by means of which liability to accidents is reduced to a minimum and a durable and comparatively cheap frog is provided. The invention has other objects which are more fully pointed out in the accompanying description.

Referring now to the drawings :m

Fig. 14 is a view similar to Fig. 4 showing a Yfurther modification;

Fig. 15 is a view showing a further modi- Iication;

Fig. 16 is a sectional view `taken on line 16-16 of Fig. 15;

Fig. 17 is a sectional view taken on line 17-17 of Fig. 15.

Like numerals refer to like parts throughout the several figures.

lVhen the frog is made of railway rails, these rails are combined in such a manner as to form the frog, the frog then consisting of wingrails, easer rails, guide rails, `point rails, etc. In describing lthe cast frog made up of cast parts, I will use these taken on line 2o taken on line on line taken on line to Fig.

same terms to designate the parts of the cast frog to correspond to the rail elements in the frog made of rails.

Referring now to Fig. 1, I have shown a construction where the left end or toe end of the frogis made entirely of cast or 'forged sections. In this construction the body of the frog is split down the middle as it were along line 2, the two sections being brought together, there being preferably a locking projection 3 (see Fig. 6) 0n one of the sections which fits into a suitable opening in the other section. In this construction `the wing rails 1, see also Fig. 6, are made integral with the guide rails 4 and the filler blocks or portions 5. The spike flanges 6 are also cast integral with the other parts. In other words this end of the section is made in two cast parts which include all the parts of the frog, and which are bolted together at suitable intervals by bolts 7. The right or heel end of the frog is made up partly of cast or forged sections, and partly of rails. In this construction, for example, the point rails 8 are made of ordinary rails (see Fig. The guide rails 4 and wing rails 1 are cast or forged and are integral with the guide and wing rails at the toe end of the frog, and are also integral with each other (see Fig. The liller blocks 9 and the heel riser 10 are separate from the other parts, and the sev` eral parts are fastened together by the bolts 7.

In F 7 which is a view similar to Fig. I have shown a modified construction wherein the iller blocks 9n are integral with the guide rail 4 and wing rail 1. In other words these liller blocks may be separate' blocks as shown in Fig. 3, or made integral with the guide and wing rails asshown in F 7.

In Fig. 2 I have shown a construction where the lett or toe end ot the block is similar to that shown. in Fig. 1, and where the right or heel end is made in cast or forged parts. In this construction the point rails 11 are integral with frog point 12, but are separate from the guide rails 4 and wing rails 1, which are integral with the guide and wing rails at the toe end of the frog. r[he filler blocks 13 may also be integral with the guide and wing rails as shown in Fig. 4, and the several parts are held together by the bolts '7.

Fig. 8 is a construction similar to that shown in Fig'. 4 except that the filler blocks 132l are separate from the guide and Wing rails 1 and 4, and the guide and Wing rail sections are solid instead of hollow, that is, instead of having the interior portion omitted, there are receiving spaces in the parts betiveen which the filler blocks are placed to receive the sides thereof.

Fig. 9 is a view similar to Fig. 8 exceptthat the Wing and guide rail. sections are hollenv insteadr of solid.

Fig. 10 is a sectional view on line 10-10 of'Fig. 2. and shows the construction at the point, the filler blocks being separate from the rest of` the frog and placed in position.

1.1 is av vieiv similar to Fig. 10 except that the outside sections are not hollow but solid and the Weight is reduced by making the outside faces with depressions 1T, the heads and nuts of the bolts fitting in these depressions. These depressions may be providedvivith ribs 19 if desired.

12 is a vieiv similar to Figs. 1() and l1 except that instead of having separate filler blocks there are portions 18 which are integral with the side sections and which engage the frog point. rthe side sections are holloived out. as shoivn.

Fig. 13 is a construction similar to Fig. el, except that the `filler bloclr section 13h instead of projecting from the face of the side sections are formed by having` these side faces turned to an angle as shoivn and are integral With the side sections. This forms a light and durable construction.

Fig. 14 is a section similar to section t except that the iiller block sections 13C are integral with the frog point 12 and the side sections are provided with receiving spaces for them.

B v making the frog in this manner l am enabled to get better castings or forgings for the different sections ivhich may be of manganese steel or alloy steel. and these parts when held in proper relationship give a greater bearing under the frog points. The chances of having a defective frog is also greatly descreased. In such a construction if any one part breaks or fails, the parts are still held in proper relation and will act Without danger to the rolling stock, Whereas if the frog was a single cast or forged piece, it would if breakage occurs be liable to cause derailment.

Figs. 15, 16 and 17 are views showing a modified construction. In this construction the entire body ofthe frog is in one piece, preferably of manganese, and there is added at 'the ends the rails 1 and 8, and these rails may be of the ordinary shape.

ln certain of the claims l have used the term cast designating certain parts of the frog` to distinguish rails which are rolled. l; am using the term cast to include also suchr parts in the event they should be forged.

1.. A, ,ailvvay frog comprising a plurality of unitary cast part-s7 said parts fitting together to form an operative structure, and means at separated points therealong for holding said parts in rigid relationship.

2. A railway frog having` one end made of unitary cast sections removably connected together, the other end being formed of rolled rails which are removably connected vsith said unitary sections to form the complete structure.

3. A railway frog comprising Wing rails and guide rails in one piece, and a separate frog point removably attached thereto.

et. A railway frog comprising Wing rails. guide rails and filler blocks in one piece, and a separate frog point connected thereto to form the complete frog.

5. A. railivayr frog comprising Wing rails and guide rails in one piece, a separate frog point and filler blocks integral with said frog point, and removable fastening devices fastening the several parts together.

6. A railway frog havingT a plurality of cast parts comprising Wing rails, guide rails and filler blocks, and means at separater points therealong which connect then'i iogether to form a solid structure.
